Abstract

The invention discloses a vehicle generator excitation module. The vehicle generator excitation module comprises a frame and at least one semiconductor unit welded on the frame. The semiconductor unitcomprises at least one chip and at least one jumper wire. One pole of the chip is welded on the frame. The jumper wire is welded on the other pole of the chip. The tail end of the jumper wire is welded on the frame. According to the invention, the technical problems of limited chip size, poor heat dissipation and low manufacturing efficiency in the prior art are solved.

Description

technical field [0001] The invention relates to the technical field of a vehicle generator excitation system, in particular to a vehicle generator excitation module. Background technique [0002] Generator excitation system is a general term for the power supply and its auxiliary equipment that supply the excitation current of synchronous generators. The excitation system is an important part of the generator. It has a great impact on the safe and stable operation of the power system and the generator itself. Excitation The main functions of the system are: 1) Adjust the excitation current according to the change of the generator load to maintain the terminal voltage as a given value; 2) Control the reactive power distribution among the generators running in parallel; 3) Improve the parallel operation of the generators Static stability of operation; 4) Improve the transient stability of parallel operation of generators; 5) When a fault occurs inside the generator, demagnetiz...
